Our soybean scouts detected brown marmorated stink bug (BMSB) in three new Virginia counties this week (Halifax, Greensville, and Brunswick). They found soybean fields in the following counties at BMSB threshold (3-5 adults + medium to large nymphs per 2-minute visual count or per 15 sweeps): Albemarle, Bedford, Fluvanna, Goochland, Greene, Orange, Rappahannock, and Shenandoah. Please see the map for more details.
When monitoring, don’t forget about our native stink bug species–we have been seeing moderate to high numbers of green stink bugs in some fields. The threshold for a normal mix of stink bug species (green, brown, and BMSB) is 5 in 15 sweeps.
